UNITED STATES-f PATENT {infr-Ien."

TOWNSEND, SAME- pLAxGE iMpRovEM-ENT IN EYELETING-MAGHINES.:

To all -whom/it may concern:- Be it known 'that I, JOSEPH F. SARGENT,A of Suffolk county, and State of Massach usetts',

have in vented ',certain'llnprovements in Eye-' letin gf'Machines "and Ido hereby declareth at the following, taken'in connection \vith,`tl 1el drawings which ,accompany and forni vpartof this specitcatiomis a description of my invenl' tion sufficient to lenable 4those skilled in" the' art to,` practice-it.

This invention-relates t0--`certain improve;

@and-set d,' the cam.l allows the'sai'd tip 'to ments in the -eyeleting-maehines patented-by me'January 6 and August 25, 1863;.num`bered,

respectively, 37,306 and-39,705,5saidf im prove'- `ments'being also applicable toother eyeletin"g machines.-

. Theimprovements consist -ina'new manner? of feeding the eyelet 'toi thefoperation jofi' the -clinchin g or setting tools,v andl in-.themchanl ism of operating the lowerI setjalsQ- in a new rconstruction or operation of thel-ho{ p"e'r;.A

als'o.in a method of adjusting-the upperset,

so' as to adapt the setting devicesl to theusej of' varying stockand eyelets.

Thevaecompanying drawings showV a ma# forms the top of a pin','s liding in such tube,

chine embodying` my improvements;

-Figure-l represents themachne partly infsection and partly in side elevation. Fig. 2is a front elevation vof iti; Fig. 3, a central crosssection of the hopper, Fig. 4, a view of rthef gate77 to the hopper. Figs. and Grespec't# ively show an elevation and section of-a modif ication of said gate. Figs-7 `andS represent,

g on an enlarged scale, front and lsectional views of the bottom of the ey'felet-chute'.,

In the drawings, a denotes the base-plate of the machine; b, the upperorstationary set, xed in the front end of an arm, c', rising from the plate a. fd, the lower or movable set; 6, .the

eyelet-h'opper, and f the inolined'chute leadingtherefrnrto the lower set, d. The lower set is fixed in the top of 'a pistou vorrod, y', vwhich 'slides vertically in a rocking arm or'v cylinder, h, hung upon va pivot, t', as seenin l. In an extension, m', from the top of the rod"'g1 a cam, l, is' formed, said cam Work- `ing on apin': or friction`roller,'-a,- and. guiding the movements of said lrod' g.. To the lower end ofthe rod g`. the` upper" end vof one arm,` n, of aftoggle-joint'is applied, the lower end of said arm being jointed to the upper end ofthe other 'a1m,p,1- of; saidA toggle, whose lowerver 1 d is jointed' toa statwfharyl'projection or {extension, pffrom the b'ase pla-'te (1.."A continuar in Fig.l7.' -As ,the'toggle-levers' raise the 'rodl rise'l-vertieally.until its lpoint has entered the eyelet, after which the cam forces the lop-of r'odfgloutvspard,y drawing' the eyelet over or th'roughthe prongs the stop-spring o, (the' eyelet slipping down upont-he cl-l nchingsur` -face of. the' Asetfuntilthe vset d and its eyelet comes" immediately under the set b,`) when the `rod and lower `set,.'. contin'uingtheir upwardmovement, force'the'lowerset, .with its impa'ledeyelet, againstthe upper set in such mann-er 'as to clinch 4the eyelet .between the i two sets and in'thework or stock. The 'low er set is madetubular, andthe point ortip 1' and kept in'positi'on by la spring, s, as seen in Fig. 1.- ..Whentheitipr in its yascent strikes the point it ort-he bottoin. of theset b, -it is heldgstatiouaiy thereby, .while 'the' set d continuesto. rise and clinches-the eyelet against the point of thelower'set toits position under vthe 4front end ofthe chute,iintoj.which thenext point Thus thelower set or the pointthereof is made both v the feeding device and,-in lconneetion 'With. the other .set, the'elinchin g device. of the machine.- j

lc velet at the front of its flange rests against the rear side of the prongs, as seen in Fig, 8, and as the point r carries the eyelet forward its lian ge is carried over the tops of the prongs, .and between them and the lower corners of the chute, the impingement of the springs bel ing upon the flange ofthe eyelet, and not upon its sides, the purpose being to prevent bend-y ing. or indentation of the sides of the eyelet,

and the application of the spring as described secures it from contact with the goods being eyeleted.

a The hopper e is made stationary', and is provided with a revolving bottom plate, 1c, upon which the eyelets rest, said plate being-fixed upon a. rotating spindle, to which movement is imparted by a ratchet and pawl on its` lower end, actuated by a connecting-romy, extending from the cam-plate m', or by any other suitable means. The inclination of the [iopper keeping the body of the eyelets at the lower part thereof, the rotation ofthe plate w and brushes m, xed thereto, carries the eyelets against a lip, a2, of a gate, b2, until by coming int-o upright position 'against said gate` t'iey slip vthrough into and slide down the ehrute. .y

The lip a2 on the gate serves to'keep back any eyelets which may come against it lying on their sides, the diameter 'of the-eyelet flange exceeding the height thereof, while if they pass nnder'said lip, lying on their top sides, the llange strikes against the top c2 of the side of the chute, and are swept back by the brushes, until, coming right side up, they slide under the lip, and the flanges pass under the inclined edge c2 of the chute, and

thence slide down the chute, the. ,fla-t, under surface of the lip keeping the eyelet from turning until it has reached the point where it is guided by both sides ofthe inclined chute.

The gate b2 is applied` to the side of the 1 chute by a set-screw, so as to be capable of b eing'raised or lowered and fastened in position for dierent sizes of eyelets.

Instead of the gate b?, a modification thereof(seen inFigs. 5 and 6) may be used. In this` modification ga ged openings are employed for di'erent sizes of eyelets, a lip on the outer surface. thereof preventing the eyelets from turning, as described.

1. The combination,iu one instrument, of the set and feeding device, made' to operate on the eyelet, substantially as above set forth.

2. Imparting the vertical movements to the movable set by means of the rod g and levers n o, arranged and operating together substantially as specified.

3. The manner of adjusting the upper set, d, withrelation to the lower set and the stook'to be eyeleted, as above set forth.

4. Themannerotapplying the stop-spriugso that the flange of the eyelet is'drawn against and over the same, for the purpose specified.'

5. The combination of a stationary hopper with a rotating disk or pla-te and a chute, as above set forth.

6. Combining with the stationary hopper an adjustable or gaged gate, substantially in the manner as above specified.

47. In combination with the vibra-ting set d, the use of the springpin or sliding pin r to feed the eyelet from the stationary chute, substantially as described.
